Straight hair really keep you bounded to a limited hair cuts and obviously they are layers or steps. So lets see what we have for you.
At Home :
Yes you shud keep yourself styled even at home. What you can do is make a BUN. Yes you heard that right. I know it sounds too pathetic and like an OLD AGE style but trust me if you have layer cut hair or step cutting and also bangs then this can make you look simple awesome.
Make a high ponytale, and make a bun there. Your first and second layer will be out. If you have bangs, they will come out as well. Divide them in sideways. NO MIDDLE PARTITION (NMP). It looks very ugly.
For Home Parties / Evening Look :
1) A high pony tale with bangs/ first n second layer out is simple and elegant and classy. The rule of NMP applies here too. This hairstyle is quick and can be done for normal to special events.
2) French braids. Try them and make sure all ur layers r tucked in as much as you can. They will give you an elegant look, but if some of the first or second layers come out or the bangs then it will make you look very classy.
3) If u wish to keep your hair open, here is sumthing really quick. Buy en elastic hair band. Let your first and second layers out in front, and let all remaining hair behind and VOILA, you look different. This is one of the most easy, comfortable, quick and beautiful style.
For Special Events:
Buy a curler or a hair roller. That would be a great instrument. So you can have a different hair type for special occasions and once you have curled or bouncy hair, you know u can do anything with them.
